| 中文摘要: |
| 针对机械密封的润滑和泄漏特性，研究发现，同时改善两特性的表面织构往往伴有较复杂的设计准则，而形式相对简单的织构设计在改善润滑性能的同时，往往导致泄漏增加。对互相矛盾的多个性能指标进行协调优化是表面织构技术在机械密封领域面临的挑战。优化算法是一种客观获得问题最优解的有效手段。鉴于此，介绍了基于单目标优化算法的表面织构形状优化研究现状，总结了基于多目标优化算法的机械密封润滑特性和泄漏特性协调优化研究的主要进展，并聚焦于同时以承载力和泄漏率为指标的螺旋槽参数和自由织构形状优化，最后分析了协调优化研究中存在的不足，并展望了其发展方向，以期进一步推进表面织构技术在密封领域的应用。 |

| In view of the lubrication and leakage characteristics of mechanical seals, it has been found that the texture designed for improving the lubrication and leakage properties always has complex design guidelines, and the texture with simple forms always leads to leakage increase while improving the lubrication property. Coordinated optimization of conflicting performances is a challenge of surface texture in mechanical seals. Optimization algorithm is an effective method to obtain the optimal solution objectively. The research progress of texture shape optimization based on single-objective optimization algorithm was introduced. The progress of coordinated optimization of lubrication and leakage characteristics for mechanical seals based on multi-objective optimization algorithm was analyzed and the optimizations of spiral groove parameters and free-form texture shape based on the objectives in term of load-carrying capacity and leakage rate were emphasized. Finally, the shortcomings of coordinated optimization research are pointed out and the development direction is prospected to further improve the application of surface texture in mechanical seals. |
